The accident could have made the ability to drive. My Dad died of brain tumors (aMONG OTHER THINGS) and he had motor control problems tward the end.
I did n otice Mr. Novak seemed to have more symparthy for the liberal position of late, perhaps the tumopr sxplains it.
Anyway, all the best for him on the outcome of his treatment, and hope his winning personality is restored to its old attitude.
